2. Description of the Related Art In recent years, with the development of a character information processing apparatus represented by a word processor, even in an office or the like,
It is common practice to operate character information on a screen.

When manipulating the character information on the screen as described above, the necessary processing is not always completed on one screen, and in practice, there are many cases where the operation over several screens to several tens of screens is required. Therefore, it is necessary to sequentially read out the necessary parts, and a method of scrolling the screen is performed as a method of implementing the method.

Conventionally, in a screen scroll technique using a mouse in a window system, the current position relative to the entire file is indicated by the position display of the menu bar, and the menu bar is used as a guide to use the menu bar with the mouse. The screen is scrolled by moving.

[0005]

As described above, in the conventional technique, the menu bar displays the current position of the file as a position relative to the entire input document, so that the user can change the relative position depending on the length of the document. It is necessary to change the degree of scrolling while deciding the target input position. Therefore, it is difficult to immediately specify the position to scroll the screen.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a screen scroll instruction support device capable of immediately specifying an arbitrary position.

[0007]

The above-mentioned object is, in the present invention, a screen scroll instruction assisting device used in a window system, which comprises input means for reading a text file displayed on the screen and each block. Extraction information instructing means for instructing the form of information to be extracted, and text processing for counting and outputting the amount of information having the instructed form for the text file read by the input means based on the instruction of the extraction information instructing means Means, storage means for storing the information amount data output from the text processing means, and display means for reading out the information amount data from the storage means and displaying the document file information in a reduced size on the screen according to the size of the window. , A designation means for designating an arbitrary position on the reduced and displayed document file information, and the position designation means. Is achieved good on the screen scroll instruction support apparatus characterized by comprising a screen scrolling means based on the position to be constant perform screen scrolling of the document file.

[0008]

The input means reads the text file and supplies it to the text processing means. On the other hand, the extraction information instructing means instructs the sentence processing means in the form of information to be extracted for each block.
The text processing means counts the information amount of the input text file according to the instruction of the extraction information instructing means. The counted information amount data is stored in the storage means. The display means reads out the information amount data from the storage means and displays it in a reduced size on the screen according to the size of the window. Here, the designation means designates an arbitrary position on the document file information displayed in a reduced size. The screen scrolling unit scrolls the screen to the position designated by the designating unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a screen scroll instruction support device according to the present invention will be described in detail below with reference to the drawings. still,
The screen scroll instruction support device according to the present embodiment is incorporated in a window system capable of displaying windows. FIG. 4 shows an example of a document file handled on the window system.

FIG. 2 shows an example of the window display of the document file shown in FIG. 4, and the document file 31 is displayed in the window 1 on the screen. Also, window 1
Adjacent to the above, the document file information reduction display unit 34 and the screen scroll bar 35 are displayed by the screen scroll instruction support device according to the present embodiment.

FIG. 1 is a functional block diagram of the screen scroll instruction support device of this embodiment.

As shown in the figure, this device outputs an input unit 11 for reading a text file displayed on the screen and supplying it to a device in the subsequent stage, and an instruction in the form of information to be extracted for each text block. It is supplied from the information feature amount instruction unit 12, the sentence processing unit 13 that counts and outputs the information amount of the text file supplied from the input unit 11 based on the instruction of the information feature amount instruction unit 12, and the sentence processing unit 13. Storage unit 14 for storing information data to be stored, and an information amount display processing unit 15 for performing processing for reading the information data from the storage unit 14 and displaying it on the document file information reduction display unit 34 beside the window provided on the screen. And a reduction information result display section 16 for displaying the reduced information after processing on the document file information reduction display section 34, and document file information by a scroll bar display means (not shown). A screen pointing position reading unit 17 that detects the position of the screen scroll bar 35 displayed on the small display unit 34, and a screen scroll that scrolls the screen based on the position data supplied from the screen pointing position reading unit 17. And the processing unit 18.

The operation of the screen scroll instruction assisting device having the above structure will be described in detail below.

First, the input unit 11 reads the sentence file 31 consisting of a plurality of lines shown in FIG. 4, and transfers it to the sentence processing unit 13. With respect to the read text file 31, the information feature quantity instruction unit 12 gives an instruction of the form of information to be extracted for each block. As an example, here, Kanji is designated as the information amount for the block 32, and Hiragana, Katakana, Kanji, and alphanumeric characters are designated as the information amount for the block 33. The sentence processing unit 13 reads the instruction parameter output from the information feature amount instruction unit 12, and based on the read data, counts the number of characters for each line in the text file 31 as shown below. To do.

The sentence processing unit 13 counts the number of Kanji characters in each line for the block 32, and the block 33
For, the number of hiragana, katakana, kanji, and alphanumeric characters is counted for each line. The sentence processing unit 13 outputs the counted number of characters to the storage unit 14.

The storage unit 14 stores the counted number of characters.

The information amount display processing unit 15 reads the number of characters per line of the stored document from the storage unit 14 and adjusts the number of characters to the size of the window. The reduction information result display unit 16 displays the reduction information result reduced according to the window in the document file information reduction display unit 34 beside the window.
The reduced information is displayed on.

Further, the screen scroll bar 35 displays the relative current position in the document file on the document file information reduction display portion 34 in a shaded manner.

When the user moves the screen scroll bar 35 from the position A to the position B as shown in FIG. 2, the screen pointing position reading unit 17 causes the position B of the screen scroll bar 35 to move to the position on the screen. The data is read and supplied to the screen scroll processing unit 18. The screen scroll processor 18 scrolls the screen of the document file 32 based on the position data so that the designated position B becomes the position shown in FIG.
The screen scroll of 4 is also performed, and the reduced information result is displayed.

[0020]

According to the present invention, the information amount designated for each block in the text file is counted line by line, and the information amount data is displayed on the document file information reduction display section on the screen. By specifying an arbitrary position on the information amount data displayed on the document file information reduction display portion, the user can immediately scroll the screen to an arbitrary position desired by the user.
